A girl of 4 years and 5 months of age was admitted as an outpatient to perform ultrasound because of painless vaginal bleeding for 2–3 days. First, on transabdominal US, the kidneys, bladder, and uterus appeared normal. A translabial perineal approach revealed a hyperaemic mass (Fig. 1a, b). One day after, MRI was performed to exclude a possible aggressive lesion. MRI revealed the mass to be in apparent continuity with the urethra (Fig. 1c). Inspection under anaesthesia revealed a prolapsed urethra (Fig. 2): a doughnut of red and purple tissue surrounded the urethra, obscuring the hymeneal orifice. The patient was treated by undergoing a resection of the prolapsed mucosa and reocclusion of the mucous membrane around a Foley catheter. Three months later we saw: normal external genitalia, normal external urethral meatus, and no mucosal ectropion. We did not see any pathological secretions.
